Description: From Reeder (1988): "In the evening (just at dusk) of 25 (+/- 2) August 1973, eruptive activity was seen by numerous residents of Atka village while they were on a U.S. Navy harbor tug that was transporting them from Atka village to Adak. The harbor tug maintained a distance of about 9 km from the northern shore of Atka Island as it passed Korovin volcano. An incandescent 10+ m wide active lava-flow channel was observed that extended from a fissure vent the northern summit of Korovin volcano to about half of the way down the northern flank of the volcano. The incandescent lava-flow channel then ended or went out of view underneath the surface. Some minor rock avalanching down the northern side of the volcano to the Bering Sea was remembered by some of the passengers. No steam emission from the shoreline and no ash emission from the summit of the volcano were noted."
